The blood pressure-lowering effect of the DASH combination diet is significantly greater in African Americans and individuals with hypertension compared to their respective counterparts.
If you are African American or have hypertension, the DASH diet (high fruits/veggies/low-fat dairy, low saturated fat) is particularly effective for lowering blood pressure. You may see greater benefits than the average person following the same diet.

The combination diet lowered systolic blood pressure significantly more in African Americans (6.8 mm Hg) than in whites (3.0 mm Hg), and in hypertensive subjects (11.4 mm Hg) than in nonhypertensive subjects (3.4 mm Hg) (P<.05 for both interactions).
